iMPRovEMEN-r IN coRN-PLANTERS.

Speoication forming part of Letters Patent No. 156,786, dated November 10, 1874; application filed To all whom t may concern Be it known that I, ROBERT A. GREEN, of Carthage, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Corn-Planters; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consistsin the construction and arrangement of a corn-planter, asl will be hereinafter more fully set forth.

In the accompanying drawing, Figure lis a plan view of my improved corn-planter. Fig. 2 is a longitudinal section of the same through the line x m, Fig. l. Fig. 3 is a plan view of the dropping mechanism. Fig. 4t is a bottom view of the same; and Fig. 5 is a section thereof through the line y y, Fig. 4.

A represents the axle, provided with driving-wheels B B, and upon said axle are secured two parallel side bars, O O. The front ends of the bars C O are connected by loops a c with a frame, E, upon which the seedboxes D D are secured. G represents the tongue, fastened to the frame E, and adjusted slightly up and down in a bracket, b, as shown. On the tongue G is secured the front end of an inclined bar, H, which extends toward the rear, as shown in Fig. 2. On the rear end of the bar H is secured a foot-rest, I, which may be adjusted backward and forward, as desired. K represents the drivers seat, which is attached to a bar or arm, J, and the front end of this -arm is, by links d d, connected with the bar or foot-lever H. The seat-supporting bar'J is fastened by means of a pin to a brace, L, attached to the parallel bars C C.

The driver, being seated upon the seat K, with his feet on the foot-piece I, can raise and lower the front part ot' the frame E, so as to regulate the depth at which the runners M, attached to said frame, will work in the ground.

The seat K may be adjusted back and forth,

as desired, by changing the links d in various holes in bar or lever H, for the purpose of balancing the weight of the driver.

In the rear ends of the bars O is mounted a shaft, N, provided with a lever, e, and scrapers f f, for cleaning the periphery of the driving-wheels B B.

In each seed-box D is a dropping mechanism, coustructed in the following manner: In the bottom of the box is a circular revolving wheel, O, provided with eightapertures, x, at

equal distances apart, forming dropping-chambers, which are in rotation brought under a cut-off, P, above an aperture in the top of the conductor R, leading to the rear of the runner M. The dropping-wheel O revolves around a central post, t', and on said post, below the dropping-wheel, are two toothedwheels, h hf, fastened together. These wheels are each formed with four curved arms or teeth, as shown in Fig. 4, and they are arranged so that the teeth of one wheel will be opposite the spaces between the teeth of the other wheel. On the upper wheel h is a lug, y, which enters a slot in a disk, 7s, attached to the under side of the dropping-wheel O, whereby said droppingwheel is revolved when the toothed wheels h h are turned on the central post t'. These wheels h h are revolved by means of a slide, S, which is slotted, as shown, and at each end of said slot is formed a tooth, m. The tooth m, at one end of the slot, is to work in the wheel It, and the tooth at the other end v is to work in the wheel IL.

The slide S extends through both seedboxes D D, and operates both the dropping mechanisms, it being slotted at both ends for that purpose. As the slide moves in one direction the tooth m moves the wheel h oneeighth of a revolution by coming against and turning one of the teeth of said wheel, the next tooth of the wheel l1. forming the stop for the movement of the slide -by coming in contact with the other side ot' the tooth m. At'

the return stroke of the slide the other tooth min like manner operates the wheel h', and by this means the dropping-wheel O is revolved one-eighth of a revolution for each stroke-of the slide S.

3. The combination of the droppingwheel l O, toothed Wheels h h', and slotted slide S, formed with the teeth m m, all constructed as described, so that the teeth of the Wheels h It Will be operated upon by the teeth m, and also form stops against them, substantially as herein set forth.

In testimony that I claim the foregoing as my own I atlix my signature in presence of two Witnesses.

ROBERT A. GREEN.
